Nuclear fusion is difficult to achieve because it requires extreme conditions of temperature and pressure to overcome the repulsive forces between atomic nuclei. Additionally, containing and controlling the high-energy reactions involved in fusion is a major technical challenge.
What else can I help you with?
Why is fusion so hard to achieve?
Fusion is difficult to achieve because it requires extremely high temperatures and pressures to force atomic nuclei to combine, releasing energy in the process. Controlling these conditions is challenging, as the nuclei repel each other due to their positive charges, making it hard to overcome this natural barrier. Scientists are working to find ways to sustain fusion reactions for practical energy production.
Which type of nuclear reaction is more important for life on earth?
1.The sun is a huge ball of nuclear fusion. 2.We here on earth use nuclear fission to produce electricity. so the answer is 2.
Can fission occur after fusion?
No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.
Why can't we control fusion?
Controlling nuclear fusion for energy production requires extremely high temperatures and pressures to overcome the natural repulsion between positively charged atomic nuclei. Additionally, containing and stabilizing the reaction within a fusion reactor remains a significant technical challenge that scientists and engineers are actively working to address through research and development.
Does the sun produce its own light?
Yes.... The sun is a star, so it produces its own light by nuclear fusion of hydrogen into helium.
Is it so that light and heat from a star are made by chemical process called nuclear fusion?
Nuclear fusion, yes. But that's not a chemical process.
Why dont we use nuclear fusion in nuclear power plants?
Because no one has been able to produce a continuous fusion reaction so far.
Are nuclear reactions and nuclear fusions the same thing?
No, nuclear reactions refer to any processes involving changes in the nucleus of an atom, which includes both nuclear fission and fusion. Nuclear fusion specifically refers to the process where two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy.
What makes it so hot inside a star?
Nuclear fusion.
How efficent is nuclear fission?
It is not possible to give an answer as there is no practical design for a fusion power plant. So far scientists have been struggling just to achieve fusion in experimental apparatus. How the energy would be extracted if and when fusion can be achieved is not known, and to get an idea of its thermodynamic efficiency you would need to know this.
Nuclear fusion to nuclear fission?
Nuclear fusion is the phenomenon in which two lighter nuclei get fused to form heavier nucleus with the production of energy. Best example is SUN and hydrogen bomb. But nuclear fission of breaking heavier into lighter with the emission of energy. Example uranium-235. So atom bomb Nuclear fusion has clean energy but fission has hazard energy
How does the sun burn so bright and so long?
It works by using nuclear fusion.
Are stars nuclear energy?
Stars produce nuclear energy by fusion Stars form when contracting dust in a planetary nebula contract and get so hot that nuclear fusion occurs. It explodes, forming a porotostar. Nuclear fusion of hydrogen atoms combining to form helium atoms is what keeps the star glowing.
Compare and contrast fusion and fission?
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
Is nuclear fusion feasable and if so do you think MCF or ICF?
Nuclear fusion is feasible, and both magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) are promising approaches to achieve it. MCF uses strong magnetic fields to confine and heat the plasma, while ICF involves using intense laser or particle beams to compress and heat the fuel. Both methods have made significant progress in recent years towards achieving sustained fusion reactions.
What is the process that A star turns matter into energy?
A nuclear reaction - either fusion or fission - is required to turn matter into energy.
Why can't they use the nuclear fusion rocket technology in commercial power production?
Rockets don't use nuclear fusion so far. The only "practical" use of fusion energy so far is the hydrogen bomb. A controlled reaction has not been possible - at least, not in a way that is economically viable.
